Before doing anything, I ask myself, "Do I have the talent to even bother?..."
Now of course the answer is a resounding, "NO!" So I find the best practice is to work on your denial, before starting anything! Just work on getting that self-defeating pride and all round lack lustre panache, into a hardened callous! Self delusion is your hard earned reward!
From there, you are just a few beers away from having the courage to commit that Cosby Sweater of a sound, to tracks! In the past, sub-mediocrity awaited... But thanks to better VST's and Melodyne? You are just that much closer to almost not sucking!
Which brings me to the second to last step: Have a few more beers and marvel at yourself in solitude!
Final step: Get an equally inebriated friend to listen to the track. That friend can then heap fake, drunken praise, dripping with euphemisms and unearned back pats, upon your sozzled soul!
There, you are done! A legend in your own basement...
